I still think the main way to prove that the Acacia patent is bullshit is to go back to the original reason that it was rejected the first time it was put to the US patent office. They found it to be "unpatentable." When the Acacia guy was grilled on it he didn't have much to say, only that the first time they didn't "understand" the technology.
It's obvious to me they just pushed their bullshit through the overworked U.S. patent office until someone bit on it.
